    Subject: iommu: add config dependencies
    Date: Sun, 20 Apr 2025 22:28:21 -0400

    commit [cfg/intel.scc: Include iommu.scc for Arrowlake boot support]
    moves the iommu configuration to a location that is included by more
    BSPs and kernel types.

    One of those kernel types is the -tiny kernel, which uses a allnoconfig
    base. Due to the allnoconfig, there are missing dependencies to allow
    the desired options to be enabled in the final .config

    Those missing options throw configuration audit warnings

    By adding the required dependencies to the fragment, it is now
    standalone and can be included from anywhere without configuration
    audit warnings being triggered.
